DynamicMesh

FColliderMesh is a minimal representation of an Indexed Triangle Mesh suitable to use with a TMeshAABBTree3.

Options used by TMeshTangents for tangents computation

FDynamicMesh3 is a dynamic triangle mesh class.

FDynamicMeshAttributeChangeSet stores a set of UV and Normal changes for a FDynamicMesh3

FDynamicMeshAttributeSet manages a set of extended attributes for a FDynamicMesh3.

FDynamicMeshAttributeSetChangeTracker constructs a well-formed set of TDynamicMeshAttributeChange objects (stored in a FDynamicMeshAttributeChangeSet).

FDynamicMeshChange stores a "change" in a FDynamicMesh3, which in this context means the replacement of one set of triangles with a second set, that may have different vertices/attributes.

FDynamicMeshChangeTracker tracks changes to a FDynamicMesh and returns a FDynamicMeshChange instance that represents this change and allows it to be reverted/reapplied.

FDynamicMeshOctree3 is an extension of FSparseDynamicOctree3 for the triangles of a FDynamicMesh3 instance.

FDynamicMeshTangents is a helper object for accessing tangents stored in the AttributeSet of a FDynamicMesh3.

Information about mesh elements modified/removed by CollapseEdge()

Information about the mesh elements modified by a call to FlipEdge()

Information about the mesh elements created by a call to SplitEdge()

Information about mesh elements modified by MergeEdges()

FMeshIndexMappings stores a set of integer IndexMaps for a mesh This is a convenient object to have, to avoid passing around large numbers of separate maps.

FMeshNormals is a utility class that can calculate and store various types of normal vectors for a FDynamicMesh.

Information about mesh elements modified/created by PokeTriangle()

FVertexInfo stores information about vertex attributes - position, normal, color, UV

Information about mesh elements modified/created by SplitVertex()

Base class for attributes that live on a dynamic mesh (or similar dynamic object)

Generic base class for change tracking of an attribute layer

Generic base class for managing a set of registered attributes that must all be kept up to date

TDynamicMeshAttributeChange represents a change to an attribute overlay of a FDynamicMesh3.

TDynamicMeshOverlay is an add-on to a FDynamicMesh3 that allows for per-triangle storage of an "element" (eg like a per-triangle UV or normal).

TDynamicMeshScalarTriangleAttribute is an extension of TDynamicMeshTriangleAttribute for scalar-valued attributes.

TDynamicMeshTriangleAttribute is an add-on to a FDynamicMesh3 that allows for per-triangle storage of an attribute value.

TDynamicMeshVectorOverlay is an convenient extension of TDynamicMeshOverlay that adds a specific N-element Vector type to the template, and adds accessor functions that convert between that N-element vector type and the N-element arrays used by TDynamicMeshOverlay.

TDynamicPointSet3 implements a dynamic 3D point set, templated on real-value type (float or double).

TDynamicVertexAttribute provides per-vertex storage of an attribute value

Forward declarations

TDynamicVerticesOctree3 is an extension of FSparseDynamicPointOctree3 for the vertices of a FDynamicXYZ3 instance (eg FDynamicMesh3, TDynamicPointSet3, FDynamicGraph, etc) This extension does several things: 1) provides a simplified API based on vertex IDs to various Octree functions 2) tracks ModifiedBounds box of modified areas

The template expansion requires that FDynamicXYZ3 has the following API: 1) a function int MaxVertexID() that returns the maximum vertex ID/index 2) a function bool IsVertex(int) that returns true if the index is valid 3) a function FVector3d GetVertex(int index) that returns the position of a vertex 4) a function FAxisAlignedBox3d GetBounds() that returns a bounding-box of the point set

TMeshTangents is a utility class that can calculate and store various types of tangent vectors for a FDynamicMesh.
